A green roof provides added insulation thus saving your household heating and cooling bills. On a large scale, e.g. whole cities, they could reduce extreme temperature fluctuations locally. Reduced stormwater runoff is another added benefit. Another way of reducing stormwater runoff is to harvest rainwater from your roof and store it in rain water tanks. Water Rhapsody’s Grand Opus rainwater harvesting system is designed to integrate with your existing water supply and automatically switches between the two when one supply is finished or cut off.
